Hi @Rohit_Varshney,
OJS does not include typsetting out of the box, but there are plugins that may help facilitate it. One of which is JATS - there is a plugin suggested in this thread: I need a Layout for my journal articles
Some journals also use external typesetting tools or services - although I cannot explicitly recommend any at this point. Others may wish to weigh in with recommendations.
Best regards,
